    I found this while searching over the net. Makes me wish I could at least speak Japanese, but what we have here is a 328 with individual throttle bodies which was ultimately tuned to 288PS (about 284bhp) at the rear wheels. I do not know the other mods to this engine, but it's safe to say the car goes like hell now not to mention having the most impressive 328 engine bay around.

    Little more info on this. With the above air cleaners and the hood installed, power is way down at 244bhp at the wheels. I bet it's due to essentially having little to no room between the ITBs and the hood.

    When I translated the Japanese web page, that is what came out. Although I am sure there is something lost in that translation.

    The 4v heads are certainly angled much better to do this sort of thing, not that it's easy either way! Look at the tank for pulling a map reading from! That thing is insane

    what tank do you speak of? the one that has the baby blue hoses connected to it? why on earth does it the vacuum lines need to be so large? very strange if thats the case.

    If one was going to spend a wad of cash to make N/A power, imo 4v is the way to start.

    my 2cents

    It looks like they are feeding all intake vacuum required items like the brake booster (large nozzle) and map signal (smaller nozzles from each port) from the one large tank unit. The vacuum tank is larger like this so a more even and smoothed out MAP signal is achieved. Getting MAP directly off of just a few cylinders connected to one line would provide a fluctuating signal. The real answer (and complicated) to providing a steady map signal on setups like this is to have a map sensor dedicated to each individual runner and then wired to provide one signal. What these guys in Japan are doing is clever enough and probably works fine.

    yeah it is ... good to hear the cars run goon on MAP to a common manifold ... I think I'm going to try that for now vs. throttle position ... maybe (unless I get a call like I did yesterday clarifying my stupidity on some issues :)).

    Really cool setup ... I remember seeing something a couple years ago from Japan ... I wonder if this is it? ... I thought it was a motorcycle TB conversion before though that I saw all completed.

    cheers

    The guy who built it is definitely the mad scientist of the Ferrari world. This is one of his mild cars, topped out at only 172.

    That is really cool ... but "THE mad scientist of the Ferrari world"? ... don't think so ... that title is taken by the V12 308 guy ;).

    Thanks for sharing! You have any other pics of mod's or projects? I figured most people doing these things were posting on the forums but I've never seen this one. The throttle bodies kinda look like the ones made by a local guy Hargett Precision also ... nice!

    cheers

    Indeed. I don't think anyone deserves the title more than Mark, aka the butcher!

    Yes THE mad scientist. The V12 308 is awesome, but....

    and I didn't even grab pics of his crazy projects like the twin turbo F50....
